摘要：

The uniaxial stress-strain behaviour of polycarbonate (Lexan) is examined. A grid technique is used to determine the inhomogeneous strain field associated with a steadily growing neck. An extension of photoelasticity is used in obtaining the stress variation along the line of symmetry in the neck. Comparing the grid and photoelastic measurements, the true-stress-stretch curve is established for polycarbonate. © 1990.
